Abstract

This utility model provides a kind of LED down, it includes COB light source (1), lamp housing (2), middleware and driving power supply (4), external driving power supply (4) and middleware socket connection, COB light source (1) and lamp housing (2) use shell fragment to be pressed into contact with technology, lamp housing (2) and middleware socket connection.As long as the lamp housing increase radiator that this utility model can realize same size just can accomplish more power, meet the light fixture function for different capacity of same size；This utility model carries out module type assembling, and the simple dismounting of assembling is light；This utility model uses COB light source to exempt from welding technology, decreases the defective products of production.It is easy to fast replacing light source.

Description

LED down

Technical field

This utility model relates to lighting field, particularly relates to LED down.

Background technology

Existing LED business Down lamp is difficult to meet the demand of various power due to the restriction of size, and such as 8 cun business Down lamps are Can only accomplish greatly 35W, if 50W to be will select the business Down lamp of 10 cun, and 8 cun of business Down lamps cannot meet heat radiation and want Ask, and if client needs the power of 8 cun of business Down lamp 35W and 50W two kinds, be just difficult to meet customer need, unless weight Newly design heat radiation, which adds the kind of light fixture, also delay the friendship phase of product.Existing COB light source is to use welding skill Art, so produces and replacing light source is cumbersome, and defective products also can increase because of failure welding.COB: integrated optical source i.e. chip On board, it is simply that bare chip conduction or non-conductive adhesive are sticked on interconnection substrates, then carries out wire bonding and realize it Electrical connection.COB integrated optical source is again COB area light source.

Utility model content

In order to solve problem in prior art, this utility model provides one.

A kind of LED down, it includes COB light source, lamp housing, middleware and driving power supply, external driving power supply and centre Part socket connection, COB light source and lamp housing use shell fragment to be pressed into contact with technology, lamp housing and middleware socket connection.

As further improvement of the utility model, described middleware is radiator.

As further improvement of the utility model, described middleware is for connecting box.

The beneficial effects of the utility model are:

As long as the lamp housing increase radiator that this utility model can realize same size just can accomplish more power, meet The light fixture of same size is for the function of different capacity；This utility model carries out module type assembling, and the simple dismounting of assembling is light；This reality Exempt from welding technology by novel employing COB light source, decrease the defective products of production.It is easy to fast replacing light source.

Accompanying drawing explanation

Fig. 1 is the LED down that this utility model uses radiator；

Fig. 2 is the LED down that this utility model does not use radiator.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described further.

When power is low when, do not use radiator, depend merely on lamp housing heat radiation itself the most much of that, see examples of implementation 2；Work as power Just can replace connection box with radiator when that high lamp housing heat radiation itself being inadequate and strengthen heat radiation, see examples of implementation 1.

Examples of implementation 1:

As it is shown in figure 1, be the LED down using radiator, it includes COB light source 1, lamp housing 2, radiator 31 and drives electricity Source 4, external driving power supply 4 and radiator 31 socket connection, COB light source 1 and lamp housing 2 use shell fragment to be pressed into contact with technical battery Connect, lamp housing 2 and radiator 31 socket connection.

Examples of implementation 2:

As in figure 2 it is shown, be the LED down not using radiator, it includes COB light source 1, lamp housing 2, connects box 32 and drive Power supply 4, external driving power supply 4 be connected box 32 socket connection, COB light source 1 and lamp housing 2 use shell fragment to be pressed into contact with technology Connect, lamp housing 2 be connected box 32 socket connection.

The mode of this novel employing external driving power supply and light fixture socket connection, simple and convenient when making assembling.

This novel employing COB light source exempts from welding technology, and COB light source, without welding, uses shell fragment to be pressed into contact with technology.

Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to Assert that of the present utility model being embodied as is confined to these explanations.Ordinary skill for this utility model art For personnel, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should regard For belonging to protection domain of the present utility model.

Claims (3)

1. a LED down, it is characterised in that: it includes COB light source (1), lamp housing (2), middleware and driving power supply (4), outward The driving power supply (4) put and middleware socket connection, COB light source (1) and lamp housing (2) use shell fragment to be pressed into contact with technical battery Connect, lamp housing (2) and middleware socket connection.

LED down the most according to claim 1, it is characterised in that: described middleware is radiator.

LED down the most according to claim 1, it is characterised in that: described middleware is for connecting box.
